Mr Surapong, who supervises the Centre for the Administration of Peace and Order, said Capo had monitored the rallies at all seven locations, particularly the Lat Phrao, Victory Monument and Asok intersections.
There were a few traffic problems, but no reports of violence, he said.
"Capo would like to thank the Thai people, both in Bangkok and other provinces, for having exercised restraint in the present situation. We hope the rallies will continue to be peaceful and non-violent," Mr Surapong said.
He said it was not predictable for how long the rallies would continue, but police had initially prepared to handle the situation for one week.
People who want to learn of any development can call hotline 1111 around the clock, or call the Narenthorn Centre at 1669 to report for information about violent incidents, or 1356 to get information on transport routes.
